You want a Star Wars MMO with lots of story and customizable Jedi? Then so be it.
MMOs in general have been fun for me, but none draw me in because of the overall lack of story and motivation. Yes, leveling up and questing is fun but for me, I like to have narrative in my experience. Because of this, Star Wars: The Old Republic has been on my personal radar for a while now. Not only does it promise a traditional MMO experience and lots of Star Wars related goodness, but it also contains the story, character development, and conversation trees that Bioware is known for. My hands-on with the game quickly made me realize that this is a game that I could easily get lost in.
